Vedic Knowledge Online

(Sanskrit: सूत्र ) Literally `thread`. Sutras as threads or aphorisms are concise statements and a technical format in which spiritual teachings have been laid out, for purposes of brevity and to allow teachers of various sampradayas throughout the ages to deliver their own commentaries on. Eg. The Yoga Sutras of Patanjali, The Bhakti Sutras of Narada.
